Roughly chop the garlic, chili and ginger and transfer to a mortar with all the limejuice and a bit of the sugar.

Grind to a paste like texture, but it's okay if theres still some small chunks, it only makes the sauce better.

Transfer the paste to a bowl and add the soy sauce, water, sweet soy sauce and the sesame seeds, stir and its ready to serve. If you dont have sweet soy sauce, you can use a bit of maple syrup tor agave to sweeten it.
